Given a list of tuples or FrameSummary objects as returned by
extract_tb() or extract_stack(), return a list of strings ready

Each string in the resulting list corresponds to the item with the
same index in the argument list. Each string ends in a newline;
the strings may contain internal newlines as well, for those items
whose source text line is not None.

Return a StackSummary object representing a list of
pre-processed entries from traceback.
This is useful for alternate formatting of stack traces. If
'limit' is omitted or None, all entries are extracted. A
pre-processed stack trace entry is a FrameSummary object
containing attributes filename, lineno, name, and line
representing the information that is usually printed for a stack
trace. The line is a string with leading and trailing
whitespace stripped; if the source is not available it is None.

This differs from print_tb() in the following ways: (1) if
traceback is not None, it prints a header "Traceback (most recent
call last):"; (2) it prints the exception type and value after the
stack trace; (3) if type is SyntaxError and value has the
appropriate format, it prints the line where the syntax error
occurred with a caret on the next line indicating the approximate
position of the error.

y)r a An exception ready for rendering.
The traceback module captures enough attributes from the original exception
to this intermediary form to ensure that no references are held, while
still being able to fully print or format it.
max_group_width and max_group_depth control the formatting of exception
groups. The depth refers to the nesting level of the group, and the width
refers to the size of a single exception group's exceptions array. The
formatted output is truncated when either limit is exceeded.
Use `from_exception` to create TracebackException instances from exception
objects, or the constructor to create TracebackException instances from
individual components.
- :attr:`__cause__` A TracebackException of the original *__cause__*.
- :attr:`__context__` A TracebackException of the original *__context__*.
- :attr:`exceptions` For exception groups - a list of TracebackException
instances for the nested *exceptions*. ``None`` for other exceptions.
- :attr:`__suppress_context__` The *__suppress_context__* value from the
original exception.
- :attr:`stack` A `StackSummary` representing the traceback.
- :attr:`exc_type` The class of the original traceback.
- :attr:`filename` For syntax errors - the filename where the error
occurred.
- :attr:`lineno` For syntax errors - the linenumber where the error
occurred.
- :attr:`end_lineno` For syntax errors - the end linenumber where the error
occurred. Can be `None` if not present.
- :attr:`text` For syntax errors - the text where the error
occurred.
- :attr:`offset` For syntax errors - the offset into the text where the
error occurred.
- :attr:`end_offset` For syntax errors - the end offset into the text where
the error occurred. Can be `None` if not present.
- :attr:`msg` For syntax errors - the compiler error message.

The return value is a generator of strings, each ending in a newline.
Generator yields the exception message.
For :exc:`SyntaxError` exceptions, it
also yields (before the exception message)
several lines that (when printed)
display detailed information about where the syntax error occurred.
Following the message, generator also yields
all the exception's ``__notes__``.
